Labelling Containers 1.21

Thanks for the patience to anyone who was waiting for this mod to be updated <3

If you find any bug, make sure to report it here or on my Discord server.

Changes:

• Removed Forge mod loader implementation
• Added NeoForge mod loader implementation
• Completely changed how configs are loaded:
  • Previously configs were created and loaded from java classes
  • Now configs are downloaded (so they can always be up-to-date) from my GitHub repository. If you don't have internet access don't worry, configs are still created on the client.

Mainly for mod developers:

• Check out FastConfigAPI's new features (the mod was completely rewritten).
• Check out VoidLib, my new mod.
